In Roadway Geometric Design II – Cross-sections and Road Types, you'll learn ...
- Cross slope design considerations for both divided and undivided roads
- Fundamental design considerations for roadsides
- Design considerations for local roads, collector roads, arterials and freeways
Credit: 4 PDH
Length: 48 pages
This course focuses on the geometric design process for modern roads and highways. Subjects covered include: cross-section elements (lane widths, shoulders, roadside design, medians, drainage channels); local roads; collector roads; rural and urban arterials; and freeways. The course contents are intended to serve as guidance and not as an absolute standard or rule.
The course objective is to give engineers and designers an in-depth look at the principles to be considered when selecting and designing roadways. Upon course completion, you should be familiar with the general guidelines for roadway geometric design.
A Policy on Geometric Design of Highways and Streets (also known as the “Green Book”) published by the American Association of State Highway and Transportation Officials (AASHTO) is considered to be the primary guidance for U.S. roadway design. For this course, Chapters 4 through 8 - Cross-Section Elements, Local Roads and Streets, Collector Roads and Streets, Rural and Urban Arterials, and Freeways will be used exclusively for fundamental roadway geometric design principles.
